Troubleshooting Finisher Communication Code C-1102

This fault typically occurs when the printer is relocated for office cleaning and the accessory signal cable becomes loose or slightly detached.

Solution 1: Check and Re-seat the Interface Harness

Loose connectors or crooked pins on the main data line are the leading cause of this fault.
  1. Shut down the copier completely from the main rocker switch and unplug the AC power cord.
  2. Locate the thick grey signal cable that connects the finisher unit to the back of the print engine.
  3. Loosen the thumb securing screws on the connector, pull the cable out completely, and check for bent pins.
  4. Align and insert the cable back firmly into the socket, tightening the thumbscrews evenly.
  5. Plug the machine back into the wall outlet and boot normally.

Solution 2: Verify Mechanical Docking and Alignment

If the accessory cabinet sits crookedly relative to the main printer chassis, the docking detection microswitch might remain disengaged.
  1. Ensure the locking bars that latch the finisher to the main printer are secured and straight.
  2. Adjust the leveling feet on the base of the finisher if the floor surface is uneven.

Steps to follow

  1. 1

    Power off and disconnect

    Turn off the main breaker switch on the side panel and unplug the main power cable.

  2. 2

    Locate accessory line

    Find the thick data wire running from the auxiliary side unit into the rear panel ports.

  3. 3

    Inspect and tighten pins

    Unplug the cable, confirm no contacts are damaged or crushed, plug it in firmly and lock the screws.
